Featuring a full-sized 34\" tall curvilinear XStat electrostatic transducer, the ESL performs more like a mini-flagship than an entry-level audiophile speaker.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThis bold loudspeaker establishes a new benchmark for price versus performance. Pushing thin film transducer technology to its limit, the ElectroMotion ESL features the most affordable full-size XStat electrostatic transducer \u003cem\u003eever\u003c\/em\u003e designed.\u003c\/p\u003e\n\u003ch4\u003eIs There a More Exciting Speaker at This Price?\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003e\"If there's a more exciting loudspeaker out there at this price, I certainly haven't heard it,\" raves Jeff Dorgay in the May 2011 issue of \u003cem\u003eToneAudio\u003c\/em\u003e magazine. \"While the year isn't yet half over, the EM-ESLs are on our short list for a Product of the Year award.\"\u003c\/p\u003e\n\u003ch4\u003eMicroPerf and AirFrame Technology\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eElectroMotion ESL's XStat electrostatic MicroPerf panel is housed within a radical aluminum and composite AirFrame similar to those found on MartinLogan's flagship products. AirFrame technology rigidifies the electrostatic panel without obstructing playable surface area or interfering with ambience enriching dipole sound radiation. At the same time, an AirFrame provides electrical and acoustical isolation, minimizing intermodulated distortion caused by vibration and resonance while enhancing imaging, low-level sonic detail, accuracy, and efficiency.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eMicroPerf design optimizes the individual holes of The EM-ESL's electrostatic panel. MicroPerf design substantially increases diaphragm radiating area, compared to early generations, without compromising structural integrity. The resulting increase in output capability and efficiency allows The EM-ESL's panel to enjoy a substantial leap in bandwidth and dynamics without growing larger. For example, The EM-ESL's XStat electrostatic panel features 129 square inches of sound radiating surface on both the front and back and a sensitivity of 91dB into 6 Ohms.\u003c\/p\u003e\n\u003ch4\u003eCLS XStat Transducer\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eOne of MartinLogan's original breakthroughs, CLS (Curvilinear Line Source) technology, has been an essential ingredient of every electrostatic loudspeaker the company has ever produced, and the ElectroMotion ESL is no exception. Proprietary manufacturing methods enable construction of electrostatic panels as cylindrical sections. Their gentle horizontal curvature solves the problem of obtaining good high-frequency dispersion from a large radiating surface without compromising overall sound quality or reliability.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eA unique XStat transducer was developed for the ElectroMotion ESL to reduce the gauge thickness of the electrostatic panel's steel stators. The reduced gauge does not alter the performance characteristics of the panel. However, as a natural byproduct of tighter build tolerances, it does increase the visual transparency of the panel. The EM-ESL's new XStat panel is so visually transparent it nearly vanishes when you're sitting and listening.\u003c\/p\u003e\n\u003ch4\u003eControlled Dispersion Sound Radiation\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eAnother key attribute of the ElectroMotion ESL is its naturally dipolar radiation pattern. A true dipole, The EM-ESL radiates sound with equal intensity from the front and back of its diaphragm, but the outputs are in opposite phase. As a result, sound waves rippling out toward the sides meet at the speaker's edge and cancel.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThat and the relatively large size of the ElectroMotion ESL's electrostatic panel cause output at the sides to be very low relative to that of a conventional loudspeaker, which in turn minimizes side-wall reflections that tend to muddle sonic detail and stereo imaging. While the reduction in output to the sides contributes to the astonishing clarity for which electrostats are revered, the energy reflected off the wall behind the speaker opens up and deepens the sound.\u003c\/p\u003e\n\u003ch4\u003eSuperb Bass Integration\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eTo seamlessly blend audio output from the high- and mid-frequency electrostatic panel to the low-frequency woofer, the ElectroMotion ESL features a proprietary Vojtko topology filter utilizing custom air core coil and low DCR steel laminate inductors, polyester film capacitors in series, and low DF electrolytic capacitors in parallel.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eA precise 8\" high-excursion, perfectly balanced, audiophile grade, doped fiber cone woofer was custom designed exclusively for The EM-ESL by MartinLogan's in-house engineering team. This woofer precisely optimizes cone suspension and magnetic flux field to produce high levels of bass output and simultaneous precise midrange. The custom woofer's rigid light-weight diaphragm eliminates cone flexure and maximizes response time to achieve remarkably low-distortion approaching that of MartinLogan's award-winning electrostatic panel design.\u003c\/p\u003e\n\u003ch4\u003eEasy Connections, Solid Adjustable Footing\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eConvenient push-style speaker terminals and curved inserts help guide speaker wire effortlessly into place. The rubber end caps on the terminal are also removable for the use of banana plugs instead of bare wire. The EM-ESL is supplied with sturdy, 1\/4-20 ETC™ spikes, which can be used to fine tune vertical wave launch, enhance stability on thick carpets, and create tighter coupling between speaker and floor to provide a tighter and detailed bass performance. Each spike is conveniently covered by removable rubber end caps if you prefer not to use spikes.\u003c\/p\u003e\n\u003ch4\u003eThe Second Coming of the Aerius?\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eLongtime MartinLogan enthusiasts are sure to describe ElectroMotion ESL as the second-coming of the legendary Aerius electrostatic speaker which debuted in 1992 and went on to sell in record numbers. The new ESL boasts 40 percent more radiating surface, a superbly integrated and authoritative bass performance, and a sensitivity rated at 91 dB. In addition, the ESL is capable of being effortlessly powered by both receivers and high-end amplifiers alike.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"Switching between the Aerius i's and EM-ESLs repeatedly revealed the latter's tremendous refinement,\" reports Jeff Dorgay in \u003cem\u003eToneAudio\u003c\/em\u003e magazine. \"Regardless of musical choice, the current model possessed an increased level of resolution that its predecessor couldn't touch.\"\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cimg style=\"vertical-align: middle; padding-right: 5px;\" alt=\"warning icon\" width=\"25\" height=\"25\"\u003e\u003cspan style=\"font-weight: bold; font-size: 14px;\"\u003eWARNING:\u003c\/span\u003e Cancer and Reproductive Harm - \u003ca style=\"text-decoration: none; color: #2f84eb;\" title=\"California Proposition 65 link\" href=\"https:\/\/www.p65warnings.ca.gov\/\" rel=\"noopener\" target=\"_blank\"\u003ewww.P65Warnings.ca.gov\u003c\/a\u003e\n\u003c\/div\u003e","brand":"MartinLogan","offers":[{"title":"New","offer_id":45981936222381,"sku":"NEW-MLEMESL-EABLK","price":1399.99,"currency_code":"USD","in_stock":true},{"title":"Demo","offer_id":45981936255149,"sku":"DEMO-MLEMESL-EABLK","price":1199.0,"currency_code":"USD","in_stock":false},{"title":"Open Box","offer_id":45981936287917,"sku":"OPEN-MLEMESL-EABLK","price":1399.99,"currency_code":"USD","in_stock":false},{"title":"Cosmetically Blemished","offer_id":45981936320685,"sku":"BLEM-MLEMESL-EABLK","price":1399.99,"currency_code":"USD","in_stock":true},{"title":"Factory Refreshed","offer_id":45981936353453,"sku":"RFRB-MLEMESL-EABLK","price":799.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3708\/1773\/files\/emesl1__56003.1687291504.3000.3000_2nd.jpg?v=1785697241","url":"https:\/\/www.audioadvisor.com\/products\/martinlogan-electromotion-esl-electrostatic-loudspeaker-black-each","provider":"Audio Advisor","version":"1.0","type":"link"}
